Quarter of students fail exam for Army

Nearly one-fourth of the students who try to join the U.S. Army fail its entrance exam, painting a grim picture of an education system that produces graduates who can't answer basic math, science and reading questions, according to a new study released Tuesday.

The report by the Education Trust found that 23 percent of recent high school graduates don't get the minimum score needed on the enlistment test to join any branch of the military. Questions are often basic, such as: "If 2 plus x equals 4, what is the value of x?"

The military exam results are also worrisome because the test is given to a limited pool of people: Pentagon data shows that 75 percent of those aged 17 to 24 don't even qualify to take the test because they are physically unfit, have a criminal record or didn't graduate high school.

Recruits must score at least a 31 out of 99 on the first stage of the three-hour test to get into the Army. The Marines, Air Force, Navy and Coast Guard recruits need higher scores.

The study shows wide disparities in scores among white and minority students, similar to racial gaps on other standardized tests. Nearly 40 percent of black students and 30 percent of Hispanics don't pass, compared with 16 percent of whites. The average score for blacks is 38 and for Hispanics is 44, compared to whites' average score of 55.
